Application filed September 8, 1898. $eria1 No.690,515. (N model.)

To all whom it may concern:

Be it known that LFREDERIOK V. WINTERS, a citizen of the United States of America, residing in the city of New York, in the State of New York,have invented certain new and useful Improvements in Radiators, of which the following is a specification.

My invention relates to improvements in radiators for heating purposes and the object is to provide a radiator of a novel and improved construction which is certain and efficient in operation, as will be hereinafter fully described, and the novelty of which will be particularly pointed out in the claims.

I have fully and clearly'illustrated my invention in the accompanying drawings, wherein Figure 1 is a side view in elevation, partly in section, of a radiator embodying my improved construction. Fig.2 isavertical central transverse section of one of the loops. Fig. 3 is a vertical central transverse section of the central short pipe or chamber. Fig. 4 is a section on the line as x of Fig. 1'. Fig. 5 is a vertical central section through the central short pipe or chamber of the group of threepipes, showing the central upward-extending hot-water feed-pipe and the downward-extend: ing cold water pipe and also showing the threaded sockets with the stud or short brace and holding rods or pieces attached thereto.

Referring to the drawings by designating reference numerals and letters, A A designate the respective end sections of the radiator, consisting of a determined and desired number of cast radiator-loops of the usual construction,comprising duplicate tubular orhollow shells of two vertical limbs 12,0pening into each other at the top and bottom, as shown, and also having pipe connections 3 4:, constituting ports at top and bottom, connecting each loop to the next adjacent loop, substantially as shown, and in the well-known man-v ner of securing the group of loops together. At the top and bottom portions of the end loops of each of the sections A A are formed bosses 5, which are tapped and closed by detachable plugs 6, preferably having threaded connection in the apertures of the bosses, and

to one of the upper-bosses is fitted a filling funnel or piece 7, provided with a turningplug 8 to open and close access to the loop and through which water may. be poured and conducted to the radiator whenever required.

13 B designate outer or end loops, and O designates the central piece or chamber, of an interposed and intermediate group of three of equal lengths and made shorter than the loops constituting the end sections or groups A A, the said parts B, B, and 0' extending downward from the top of the whole group to about midway of the length, as shown in Fig. 1 of the drawings, and having tapering lower ends 9, which are provided with threaded apertures, those of the loops B B having small pipes 10 11 screwed therein, which pipes at their lower ends are turned laterally and open into the inner loop of each side section, as shown, the lower ends of the said pipes being connected to the loops byany well-known means. The aperture in the lower end of the central part 0 is of greater diameter than the apertures of the other pieces B B and has suitably connected thereto a cold-water pipe 12, which leads to a cold-water duct of aheater. (Not shown.) The lower ends of the short loops B B are connected to the adjacent loops of the main or longer loops of the radiator by bosses 21, as indicated in the drawings. In the chamber of the part 0 extends centrally a vertical hot-water pipe 13, reaching at its upper end adjacent to the top of the chamber and passing downward loosely through the coldwater pipe 12, so that a cold-water-circulating space is formed between the pipes. The lower end of the hot-water pipe is designed to be connected to the heaterin such manner that when the circulation is established'by the effects of the heater the heated water will be carried upward and discharged into the upper end of the chamber and from thence create and maintain a circulation in the well-known manner. It will be perceived that all the rest of the loops of the radiator may be formed of two limbs. This central piece or chamber 0 is of a single interior formation, it being made to receive the operative interposition of the central vertical hot-water pipe, the oper ation of the flow through which pipecreates, induces, and maintains the requisite oiroulation.

Hinge-seats ll are formed in the inner loops of the group adjacent to the space and on the opposite sides, to which doors (I d are tor.

hinged and supported to close the space or chamber below the central short group of loops and pipe, as shown in dotted lines in Fig. 1 of the drawings. 7 To strengthen the intermediateand central group or shorter pipes, they are formed with bosses 16 on their facing or "opposing faces at? their upper and lower portions, which are formed with threaded sockets in which are fitted and in which engage adjusting and strengthening studs 20, whereby the respective parts are held securely in relative position.

An ornamental top piece '2l'maybe fitted over the top and upper portion of the loops, as indicated. In the drawings this top piece is shown as raised from its seat on the radia- Any proper water-heater may be used in connection with this radiator. It may be inclosed within the chamber closed by the doors-for instance, in a suitable compartment below that containing the radiatorthe only essential being that it shall have circulating connection with the depending coldwater pipe and with the vertical hot-water -pipe inclosed therein.

The operation is as follows: The cold water is introduced through the filling-tube or funnel and flows down the tubes of the loop into which the filler opens, thence through the ports or openings at the bases of the first group or half of the sections, and eventually reaching to the top of the radiator and finding its way through the respective ports and openings throughout the radiator, eventually rising and resting at the desired common height, circulating in the operation of receiving the requisite supply through the top opening of the farther series of loops, and falling into the accumulated water in that part which has flowed into it through the small pipes at the base of the communicating lower ends of the central short series or groups of pipes. At the same time the cold water flows down the depending cold-water pipe leading from the lower end of the pipe or chamber 0 to the heating source and of course up the hot-water pipe to equilibrium. The heat now being applied to theheater, the water becomes heated and is forced up through the hot-water pipe 5e lation through the heater and is conducted to 5 5 the hot-water pipe and is discharged at the top, and thus circulates until all the water in the radiator becomes heated.

The heater may consist of a suitable device inclosed in the chamber or space below the short section of pipes and shielded from view by the doors closing that part or space in the radiator; V

'What I claim is 1. A radiator comprising two outer sections of loops having communication at their tops and bottoms, a plurality of shorter loops interposed between the upper portion of said outer sections and communicating therewith at top and bottom, a central chamber 0 between the shorter loops and in communication therewith at top and bottom, oppositelydisposed pipes leading from the lower ends of the outer pipes of the shorter loops and opening into the bases of the adjacent loops of the outer sections, a cold-water pipe connected to the lower end of the central chamber 0, and a hot-water pipe of less diameter inclosed in the cold-water pipe and extending vertically into the central chamber, substantially as described.

2. In a radiator, the combination with two series of communicating sections or loops, of a central series of shorter pipes or loops communicating with the side sections, a central chamber C intermediate of the short pipes, a cold-water pipe connected with the central chamber 0, and a hot-water pipe extending through the cold-water pipe and projecting substantially to the top of the central cham- 9c ber, substantially as described.

In testimony whereof I aflix my signature in presence of two witnesses.
